SHEET-METAL TILE.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed March 21,1907. Serial No. 363,606.

T0 at 1071/0721, it may concern:

Be it known that l, SEWARD l-loMEa CALK- me, a citizen of the United at Baltimore, in the State of l\lar vland, have invented certain new and useful Improve- States, residing ments in Sheet-Metal Tiles, of which the fol- 1 lowing is a specification.

This invention relates to improvements in the construction of tiles for wall finish.

The invention has several objects in View; one ob ect being to provide the tile on its opposite edges with backward projecting flanges which incline inwardly for the several purposes of (1) forming at the back of the tile what may be termed an undercut with which the plastic cement on the wall may engage to effect a secure bond, (2) form- 5 ing edges which are beveled or recede from the front surface so that at the front the edges of adj oining-tiles will closely abut, and (3) forming concealed spaces between the edges of adjoining tiles,

tion by injecting cement in a semi-fiuid condition.

The improved tile is constructedwith the view of being set in plastic cement on the wall, or nailed to a wood surface. It is well understood that this class of tile may be glazed, painted or enameled in any color.

The drawings illustrate the invention.

Figurel is a front perspective view of an improved tile having the features of my invention. Fig. 2 is a back view ofthe tile shown in Fig. 1. Fig. 3 is an outer or front view of severaltiles'as they'appear when being placed in position. Fig. 4 shows a top view of one side edge of a tile. Fig. 5Tisa horizontal section taken on the line 55 of Fig. 3.showing the position of a joint of two tiles above the central cut-out portion of the tile next below. Fig. 6 is a sectional view on a larger scale of one tile and the adjoining tiles, and the cement on the wall, to show the'relation of the various parts. Fig. 7 is a back .view of a. tile ha ing the features of my invention, but modified from the form shown in Figs. 1 to 6 inclusive, by having one bend less in the edge-flange. Fig. 8 is a front per pective view'of the tile shown in Fig. 7. Fig 9 is a cross-section of the tile shown in Figs. Tand 8.

Inasmuch as all the. features of the form of tile shown in Figs. 7, 8 and 9 are also in the other form shown in Figs. 1 to 6 of the draw ing, I will first describe the construction of ends of two which spaces-may be i filled after the tiles have been placed in posithe form illustrated in said Figs. and then it will only be necessary to describe the additional features of the tile shown in.

Figs. 1 to 6.

Referring to Figs. 7, h and 9 the outer or front face of the sheet-metal tile is designated by the numeral, 1, and in practice this face may be painted, japanned or enameled, and the back is designated, 2. The opposite edges of the tile are provided with a 7, 8 and 9,

flange, 3, which from the front face projects backward and also inclines inwardly thereby forming as shown in Fig. S). what may be termed an undercut, when the back, 2, of

the tile is pressed against plastic cement on the wall, the cement will engage with the said undercut part, 4, of the flange, 3, and when the cement has set or hardened it will securely hold the tile. This beveling of the flange, 3, from the front face also results in forming prominent edges, at the front which insures that the edges of adjoining tiles will abut closely and make close fitting joints at the front. It will also be understood that when the prominent edges, 5, of

two of these beveled or backward-receding flanges are in contact, they will form a triangular shaped concealed s ace by the edge of one inclined flan e, 3, of one tile bearing on or in contact wit a flat lateral flange, 8, of the adjoining tile. This is plainly shown in Fig. 6, where the concealed space is designated, 6. The concealment here referred to is concealment from front view after the tile have been set. Those spaces, 6, serve a useful purpose in that they afford room for the reception of semifluid cement which may be injected or iplaced in the spaces during the operation 0 securing the tiles in position. The semifluid cement will harden in the space, 6, andmake a perfectly tight joint.

The backward-projecting flanges,-3, may be on all the edges of the tile but at least are on opposite edges, therefore one or more of said flangeshave a notch, 7, which serve to vent the air from behind the tile when pressing the tile closely in contact with the plastic cement on the wall. It will also be seen by reference to Figs. 7, 8 and 9 that a flange, 8, projects laterally from one side and one end andsaid latera flange, 8, is in a plane that is parallel with the plane of the front face, 1, V Vhere the tile is rectangular the said lateral flange, 8, will pro ject from but. two edges; the other two edges will have only the beveled flange, 3. In

the bevel flan e, 3, at

order to ernii't. of securing the tile to a wood surface t e lateral flanges, 8, have perforations, 9, toreceive small nails. hen the tiles are in p osition on a wall, the edge of bevel flange, 3, at two right-angled edges of some additional features, which will now be described. A flange, 10, is bent from or attached to the lateral flange, 8; this flange, 10, projects at a right angle with respect to the flange, 8, and is also at a ri ht angle with respect to the front face, 1, of the tile as seen in Figs. 1 and 6. The part in these Figs. 1 to 6, that corresponds to the lateral flange, 8, in Figs. 7, 8 and?) has a central cut-out portion, 11, and the ends of the said flange, S, at each side of the cut-out are bent back to form bevel s as at, 12, thus making. the cut-out nearest the outer or front surface broader than at the back. In placing the tiles against plastic cement and applying pressure, the cement. will press through the narrow back part of thecut-out portion and spread forward into the broader part of the same, and form a bond or key.

From the description herein given the manner of applying the tiles or placing them in position Wlll be understood.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is,-

1. The combination of two tiles each having on all of its opposite edges a flange, 3, which projects backward and also inclines inwardly and forms at the back parallel opposing undercuts, and two of said adjoining inclined flanges provided with an outward lateral flange, 8, which has position in a plane parallel with the front face of the tile, and the edge of one of said inclined flan es, 3, of one tile bearing on or in contact wit a flat lateral flange, 8, of the other tile, thereby forming a joint having a concealed space.

2. A sheet-metal tile having around its edges a flange projecting backward and also inclining inwardly and forming an undercut surrounding its edges, and two of said inclined flanges provided with an outward border flange, 8, Whose surface is parallel with the front face of the tile, and a flanged edge, 10, rojecting at a right-angle with respect to t c said border flange, S.

In testimony whereof I afiix my signature in presence of two witnesses.
